Problems solved by technology

The heat treatment process of sawtooth needs to go through cleaning and drying, quenching, cooling, low-temperature tempering and high-temperature tempering. Generally speaking, the material is tempered once after passing through two tempering furnaces. High-temperature tempering needs to be tempered 8 times, but 16 The space occupied by a tempering furnace is very large, which is obviously impractical. Therefore, a device is needed to enable the sawtooth to run back and forth in the tempering furnace. While ensuring reliable tempering, it can save the number of equipment and reduce the cost of the equipment. Floor area

Embodiment Construction

[0038] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0039] Such as Figure 1-21Shown is a heat treatment equipment for steel used in sawtooth, including a washing and drying machine 1 used in the first process, a quenching furnace 2, a cooling oil tank 3, a low-temperature tempering furnace 4 and a high-temperature tempering furnace 6 used in the second process. The steel material is Longsheng X32 steel strip. Here, passing through the two-section tempering furnace is defined as one-time tempering. The first process: the cleaned and dried steel strip passes through the quenching furnace 2, enters the cooling oil tank 3 to cool, and then enters the two-section tempering furnace. The low-temperature tempering furnace 4 and the cooling water tank complete the first tempering, where the tempering temperature is set to 580 degrees Celsius, the passing speed is controlled by the traction frequency converter...

Abstract

The heat treatment equipment comprises a high-temperature tempering furnace, sawtooth steering devices are arranged on the two sides of the high-temperature tempering furnace, the sawtooth steering devices comprise workbenches, and the workbenches comprise the first workbench arranged on the left side of the high-temperature tempering furnace and the second workbench arranged on the right side of the high-temperature tempering furnace; the first workbench is provided with two turning rings, the second workbench is provided with a turning ring, the first workbench and the second workbench are provided with a plurality of limiting cylinders, and the limiting cylinders are sequentially arranged to be in an arc shape. The saw teeth can be automatically steered during heat treatment.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a heat treatment equipment for steel used in sawtooth. Background technique [0002] In the production process, saw teeth need to go through edge hanging, laser cutting, heat treatment, sandblasting, welding teeth, tooth grinding and other processes, especially in the process of heat treatment, which can greatly improve the performance of steel and make it have good Strength, hardness and toughness. The heat treatment process of sawtooth needs to go through cleaning and drying, quenching, cooling, low-temperature tempering and high-temperature tempering. Generally speaking, the material is tempered once after passing through two tempering furnaces. High-temperature tempering needs to be tempered 8 times, but 16 The space occupied by a tempering furnace is very large, which is obviously impractical. Therefore, a device is needed to enable the sawtooth to run back...
